COEFFICIENT OF PHOTOSYNTHESIS ECONOMIC EFFICIENCY AND YIELD OF SPRING SOFT WHEAT CULTIVARS AT DIFFERENT LEVELS OF NITROGEN NUTRITION
Abstract
The results of 4-year researches on the determination of the coefficient of photosynthesis economic efficiency of 15 spring soft wheat cultivars and varieties of RUE ”Research and Practical Centre of NAS of Belarus for Arable Farming” breeding are discussed in the article. The closeness and direction of the grain yield and the mentioned coefficient using different rates of nitrogen fertilization (100 and 160 kg/ha of active substance) are shown. The correlation of the coefficient with the thousand-kernel weight and spring wheat grain number per area unit is presented.
